wkom it mag concern:

it known that I, KARL VoLLER, engia subjeot of the German Emperor, re- ..-io.-..a-g st Dusseldorf, l7 Jiilieheistrssse', Gee nee have invented certain new and 's-sis; improvements in Automatic Firing ehz-misin end i do hereby declare the folo a full, clesr, end exoet deseri *ention, such as will enable 0t, 1- the art to which it ep p'erteins to sod use the This invention relates to a device by which a gun is mitoinstieslly fired. soon ss tbe breech is closed, breech the trigger ilevioe is so moved tbot the i'elesse of the firing bolt 01' hammer occurs as soon. as the olosiogmovement is finished.

'l'he device is preferably so arranged that in the event oi v e. misnre the tumor device i i v 0Q can be sctus'teo by fiend. WEiSllOUt the news on y for again opening the breech.

Two embodiments oi the invention are illustrated in the accompanying drawings.

Fig. 4 is a sectional plan showing the posit-ion of the arts at the oeginnin oi the movement of t e sear for firing. 1* is 5 is e modification in horizontal longitudinsl section showing the ports in the osition w iioh they have when the firin can e psvfoi'ined s,- hend, Fig: 6 is a (leteil view of the sear.

in. the position shown in Fig. The pin 2 5 carries at second army which, when the arm d is turned as aforesaid, is itself turned outwards end thus presses in the same direction the sear g pivoted in the Wedge until the sear has the position sh own in Fig. 2. In pushing 6 the wedge fully home, the sliding piece a has been pushed so far to the left that the arm 0! becomes disengaged from the point of the sliding piece c, this movement of the letter to the left being due to the engagement of a pin 6 which it carries in an inclined slot 72, in the The messing back of the sear by means of be srmfreleoses the firing bolt and fires the gun. As soon as the arm (1 has disengaged itself from the sliding piece a, the 7 seer g is turned heel: into the normal osition as shown in Fig. 3, by the torsion o the spring i surrounding its pivot.

- Should the automatic notion foil, the sear 9 can be drawn back from the position shown 7. in Fig. .3 into the tion shown in Fig. 2 by grasping the hendlo it for firing by bomb The automatic iii'ingdevice can eesiiy be put out of action by removing either the slidmg ioee c or the leverf from the breech, or 8( by isengegin the pin carried by the sliding piece c from the slot h and withdrawing the slidingpieoe.

In bigs. 54 a bolt Z is rotatsbiy mounted on the gun barrelto set as a stop. This bolt 8: extends into a osvity in the sear o and has a leterol projection m which enters a groove n in the side of the said cavity, this groove'being extended as an snnuder groove around the closed end of the cavity. 9C

In the position shown in Fig, 5 in which the sear is fully home over the bolt Z, the latter oen be turned by e handle 9 through an angle of 90, so thet the projection m passes into the annular extension of the groove 1'1- 95 and thus revents the sear froni'being iimwn bsokwer s. If the bolt Z is turned into the lest mentioned position When the Wedge is not fully home, the sear 0 will be prevented from moving home when the lever b (Fig. 1) 10 ismoved to fully close the breech, this position of the parts being shown in Fi 7. i

The length of the bolt Zis such t et at the moment of fully elosing the breech, the sear 0 is so for book that the filing bolt is released 10 end "the eherge fiiecl. Should e. mis'fiie oeeur in this construction, the bolt 1 istui'ned into the position in which its projection can enter the groove n in the sear o as shown m Fig. 5, so that by pulling the handle p the gun can be fired.

I If" it is desirable to throw the automatic firing device out of action, it is only necessary to leave the bolt 1 in the osition shown in E ig." 5, so that the sear 0 Wi 1 not be held back when the breech is closed.

The invention may also be applied to breeches having a screw closure.

Havin now particularly'described and ascertaine the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In an automatic firin device for guns, the combination, with the ring mechanism, a trigger to cook and release the same, and a breech closure, of means automatically actuated simultaneously with the final breech closing movement to operate the trigger to cock and release the firing mechanism, said trigger bein also operable inde endently of the reach 0 osure in case of mis re.

2'. In an automatic firing device for uns, the combination, with a breech bloc of means to close the same, a trigger separate from the breech closing means to cook and release the ring mechanism," and means arranged to be brought into action automatically by the final closing movement of the breech to operate the trigger to fire the gun.

3. In an automatic firing device for guns, the combination, of a breech block, a breech closing handle, a trigger to cock and release the firing mechanism arran ed to be operable independently of the hand e, and means actuated by the final closing movement of the handle to operate the trigger to fire the gun. 4. In an automatic firing device for guns, the combination, of a breech block, a breech closing handle, a sear, and a two-armed lever arranged with one arm in contact with the sear and the other in the ath of the final closing movement of the andle, whereby the gun is automatically fired upon the completlon of the breech closing movement.

5.. In an automatic firing device for guns, the combination, of a breech closing handle, asear separate from the handle and arranged to cock and release the firing mechanism, a

two-armed lever arranged with one arm in contact With the sear and the other in the path of the final closing movement of the iandle, whereby the gun .is automatically fired upon the completion of the breech 0105- 5 ing movement and in case of'misfire the firing mechanism may be cooked and agaih released Without opening the breech.

6. In an automatic firing device for guns], the combination, of a breech block, a breech 6 closing handle, a sear, and a two-armed lever arranged with one arm in contact with the scar and the. other in the path ofthe final closing movement of the handle, a detent carried by the handle and arranged to engage 6 one arm of the lever, and means to retract the detent to release the lever and sear,

whereby the gun is automatically fired and i the sear returned to its normal position upon the rcompletion of the breech closing move- 7 ment.

7. In an automatic firing device for guns, the combination, of a breech block, a breech closing handle, a sear se arate from the handle to cock and release t e firing mechanism, a two-armed lever arranged. with one arm opposite the scar and the other arm in the ath of the final closing movement of the andle, a detent mounted for sliding move ment in aslot in the handle and arranged to 8 enga e one arm of the lever, a in carried by the etent and arranged to ri e upon an inelined surface to retract the detent to release the lever, and means to return the sear to its normal position when the lever is released, whereby the gun'is automatically fired upon the completion of the breech closing move ment and the sear then returned to its normal position, and whereby in case of misfirc the sear may be operated by hand to cook and release the firing mechanism without again reopening the breech.

In testimony whereof I have hereunto af fixed my signature. in the presence of two witnesses.
